Kostadin Kushlev, Ph.D.

PI of the Happy Tech Lab, Georgetown University, Washington, D.C.

Digital technology promised to make us more connected, informed, and productive. Dr. Kushlev studies its real costs to health and well-being, from the obvious to the ones we barely notice. His research spans social media and the rapid rise of AI and large language models (LLMs). At its center is digital well-being, including everyday questions such as whether a digital detox actually helps. He is an Associate Professor of Psychology at Georgetown University, where he directs the Happy Tech Lab.

He earned his Ph.D. from the University of British Columbia in 2015 and spent three years as a Postdoctoral Research Associate at the University of Virginia.

His research is supported by a $1.5 million R01 from the National Institute of Mental Health. As Principal Investigator, he leads a study of how social media exposure shapes adolescent mental health (2024 to 2028). He also directs a McCourt Tech and Public Policy Program project on the costs and benefits of social media legislation (2025 to 2026). Earlier, he was a scientific collaborator on Greater Good in Action 2.0, a John Templeton Foundation initiative led by Dacher Keltner. His distinctions include Georgetown's Dean's Excellence in Teaching Award (2026), Fellowship in the Society of Experimental Social Psychology (2023), an APS Rising Star award (2021), and a $150,000 Vanier Graduate Scholarship that funded his doctoral training. He was elected to Phi Beta Kappa as an undergraduate at Reed College. A full record is on his CV.

His theoretical work appears in Psychological Bulletin, Current Directions in Psychological Science, and Current Opinion in Psychology. His empirical work appears in Psychological Science, Emotion, Journal of Experimental Social Psychology, and Social Psychological and Personality Science. All of his papers are here.
